I looked into updating nodejs on tiddlyspace.com to see if it would address problems with twikifier but discovered that I couldn't update node without updating a bunch of the npm installed modules: Changes in APIs. Given the time constraints this evening that was more than I was willing to contemplate, so some other time. It does point out, however, that both twikifier and twsock need to be packaged in a way that allows for easy deployment (like TiddlySpace itself).
